Optical disc cake box

ABSTRACT

The present invention describes an optical disc cake box. The optical disc cake box has a stencil layer and a cone-shaped body. The cone-shaped body is integrally formed with the stencil layer by the injection molding process so that the optical disc cake box has a better decoration, artistry and advertisement. Efficiency of manufacturing the optical disc cake box is improved to meet mass production requirements.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an optical disc cake box, and inparticular to an optical disc cake box for storing a plurality ofoptical discs and having better decoration, artistry, and advertisement,and for which efficiency of manufacturing is improved.

2. Description of Related Art

Optical disc cake boxes and optical disc slim cases are commoncontainers for storage of optical discs. There are a variety types ofoptical disc cake boxes and optical disc slim cases available on themarket. Reference is made to FIG. 1. FIG. 1 illustrates a conventionaloptical disc cake box for storing different types of optical discs, suchas, for example, compact discs, laser discs, video CDs, and DVDs. Theoptical disc box cone 5 is hollow and cone-shaped and has an opening atits bottom. The optical disc box cone 5 has a disc-receiving space 51for storing optical discs. A plurality of protrusions 52 arehorizontally positioned at the bottom of the optical disc box cone 5 andused to connect with a lower cover 6. An annular protrusion fringe 61 ispositioned at peripheral of the lower cover 6 and has a plurality ofgrooves 62 corresponding to the protrusions 52 of the optical disc boxcone 5. When the optical disc box cone 5 is placed on the lower cover 6,the optical disc box cone 5 is rotated with respect to the lower cover 6so that the protrusions 52 are inserted into the corresponding grooves62. Thus, the optical disc box cone 5 is combined with the lower cover6.

However, all conventional optical disc cake boxes are virtuallyidentical in appearance. It is difficult to make a consumer notice theboxes because the optical disc cake boxes lack decoration, artistry, andadvertisement. Although stickers having characters and drawings areapplied to surfaces of the optical disc cake boxes, stickers need to beadditionally prepared. Besides, it is time-consuming and laborious tohave stickers applied on the surfaces of the optical disc cake boxes.Thus, efficiency of manufacturing the optical disc cake boxes cannot beimproved and cannot meet mass production requirements.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an optical disc cakebox. The optical disc cake box has better decoration, artistry, andadvertisement, and is efficiently manufactured in accord with massproduction requirements.

To achieve the object of the present invention, the optical disc cakebox comprises a stencil layer and a cone-shaped body. The stencil layerhas characters and drawings, and the cone-shaped body is integrallyformed with the stencil layer by injection molding. Thus, the stencillayer is positioned on a surface of the cone-shaped body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following detailed description is of the best presently contemplatedmodes of carrying out the invention. This description is not to be takenin a limiting sense, but is made merely for the purpose of illustratinggeneral principles of embodiments of the invention. The scope of theinvention is best defined by the appended claims.

Reference is made to FIGS. 6 and 7. FIGS. 6 and 7 illustrate an opticaldisc cake box of the present invention. FIGS. 2 to 5 illustrate themanufacturing process of an optical disc cake of the present invention.According to the manufacturing process of the present invention, astencil layer 2 is pre-defined, transparent, and made of plastic. Thestencil layer 2 is annular and thin-walled, and has a pattern 21 withdecoration, artistry and advertisement. The pattern 21 may be charactersor drawings.

The stencil layer 2 is moved into a cavity 41 of a female die 4 of amold (as shown in FIG. 2) by a jig 3. The stencil layer 2 is separatedfrom the jig 3 by blown air so that the stencil layer 2 is applied to aninner surface of the cavity 41 of the female die 4, as shown in FIG. 3.Then, the jig 3 is moved and a male die 5 of the mold is combined withthe female die 4 by mold clamping, as shown in FIG. 4.

The mold is used in an injection molding process. A cone-shaped body 1of the optical disc cake box is manufactured by insert molding andwithin the mold, as shown in FIG. 5. The cone-shaped body 1 isintegrally formed with the stencil layer 2 by the injection moldingprocess so that the stencil layer 2 is positioned on a surface of thecone-shaped body 1.

Reference is made to FIGS. 6 and 7. The optical disc cake box of thepresent invention includes the cone-shaped body 1 and the stencil layer2. The cone-shaped body 1 is integrally formed with the stencil layer 2by the injection molding process so that the optical disc cake box has abetter decoration, artistry and advertisement as a result of the pattern21 of the stencil layer 2. The cone-shaped body 1 has a disc-receivingspace 11 for storing optical discs. A plurality of protrusions 12 arehorizontally positioned at the bottom of the cone-shaped body 1 and usedto connect with a lower cover (not shown).

According to the present invention, the cone-shaped body 1 is integrallyformed with the stencil layer 2 by the injection molding process,without applying stickers on the cone-shaped body 1. Thus, manufacturingprocess for the optical disk cake box is much easier and efficiency ofmanufacturing the optical disk cake box is improved in accord with massproduction requirements. Besides, the cone-shaped body 1 is integrallyformed with the stencil layer 2 by the injection molding process so thatthe stencil layer 2 will not be stripped off.

While the invention has been described with reference to the preferredembodiments, the description is not intended to be construed in alimiting sense. It is therefore contemplated that the appended claimswill cover any such modifications or embodiments as may fall within thescope of the invention defined by the following claims and theirequivalents.

1. An optical disc cake box, comprising: a stencil layer havingcharacters and drawing; and a cone-shaped body integrally formed withthe stencil layer by an injection molding process, wherein the stencillayer is positioned on a surface of the cone-shaped body.
 2. The opticaldisc cake box as claimed in claim 1, wherein the pattern includescharacters or drawings.
 3. The optical disc cake box as claimed in claim1, wherein the pattern includes characters.
 4. The optical disc cake boxas claimed in claim 1, wherein the pattern includes drawings.
 5. Theoptical disc cake box as claimed in claim 1, wherein the cone-shapedbody has a disc-receiving space for storing optical discs, and aplurality of protrusions are horizontally positioned at a bottom of thecone-shaped body and used to connect with a lower cover.
